help me lay s10frame on 20's

i was lookin at a member on here (layingbodyon20's) his truck is hot an i had been wanting to put 20's on mine but im jus going to be paying for it an i want to see what has to be done to firewall so i can explain what i want done. Some pics would help from anyone who had to do it to their truck. I already know i will have to get ride of my aircondition cause i busted it first day i got airbags. i just want my body work done before i paint it.
